Scope

This document specifies a method for determining the tensile properties of pipes made of unplasticized
poly(vinyl chloride) (PVC-U), oriented unplasticized poly(vinyl chloride) (PVC-O), chlorinated poly(vinyl
chloride) (PVC-C) and high-impact poly(vinyl chloride) (PVC-HI, PVC-M or PVC-A), and in particular the
following properties:
— the stress at yield and stress at break;
— the elongation at break.
NOTE The general method of test for the determination of the tensile properties of thermoplastics pipes is
given in ISO 6259-1.
This document also gives, for information purposes only, the corresponding basic specifications in
Annexes A, B, C and D.
